I have a problem that I just can't seem to figure out.
Here's the problem: The drawing (Click Here) shows a block (m = 1.6 kg) and a spring (k = 325 N/m) on a frictionless incline. The spring is compressed by x_o = 0.35 m relative to it's unstrained position at x = 0 m and then released. What is the speed of the block when the spring is still compressed by x_f = 0.14 m?
I applied the whole Ef = Eo equation but did not get the right answer.
I used sin 30 to find h_f.
So this is what I used:
V_i = 0
V_f = what I'm looking for
h_i = 0
h_f = .5
k = 325
x_i = 0.35
x_f = 0.14
Any help on this problem would be greatly appreciated.
Thanks in advance.
